# Memristor Equations: Incomplete Physics and Undefined Passivity/Activity

@article{Sundqvist2022MemristorEI, title={Memristor Equations: Incomplete Physics and Undefined Passivity/Activity}, author={Kyle M. Sundqvist and David K. Ferry and Laszlo B. Kish}, journal={The Random and Fluctuating World}, year={2022} }

In his seminal paper, Chua presented a fundamental physical claim by introducing the memristor, “The missing circuit element”. The memristor equations were originally supposed to represent a passive circuit element because, with active circuitry, arbitrary elements can be realized without limitations. Therefore, if the memristor equations do not guarantee that the circuit element can be realized by a passive system, the fundamental physics claims about the memristor as “missing circuit element…

In 1971, Chua defined an ideal memristor that links charge q and flux φ. In this work, we demonstrated that the direct interaction between physical charge q and physical flux φ is memristive by…

An Experimental Proof that Resistance‐Switching Memory Cells are not Memristors

- ChemistryAdvanced Electronic Materials

The results unambiguously show that electrochemical metallization memory cells are not memristor, and cast doubts on the existence of ideal memristors as actual physical devices that can be fabricated experimentally.

Reply to arXiv: 2102.11963, An experimental demonstration of the memristor test, Y. V. Pershin, J. Kim, T. Datta, M. Di Ventra, 23 Feb 2021. Does an ideal memristor truly exist?

- ChemistryArXiv

A prototype device is developed and experimentally demonstrated that the direct q-φ interaction could be memristive, as predicted by Chua in 1971, and meets three criteria for an ideal memristor: a single-valued, nonlinear, continuously differentiable, and strictly monotonically increasing constitutive φ-q curve.

Resistorless Memristor Emulator Using CFTA and Its Experimental Verification

Comment on "If it's pinched it's a memristor" by L. Chua [Semicond. Sci. Technol 29, 104001 (2014)]

Correcting the wrong statements in Chua's paper is done, which leads the author to the erroneous conclusion that charge-voltage curves of any memcapacitive devices should be pinched at the origin.

The case for rejecting the memristor as a fundamental circuit element

- ChemistryScientific Reports
- 2018

This report investigates the assertion that the memristor is a fundamental passive circuit element, from the fresh perspective that electrical engineering is the science of charge management, and demonstrates with a periodic table of fundamental elements that the 2008 mem Bristor is not the 1971 postulate and neither of them is fundamental.

The Missing Memristor has Not been Found

- ChemistryScientific reports

It is maintained that the originally hypothesized real memristor device is missing and likely impossible, and the argument is illustrated also by finding an ideal mechanical Memristor element and purely mechanical memristive systems, and hypothesizing a real mechanical mem Bristor device that requires inert mass just like the 1971 implied device requires magnetic induction.

On the physical properties of memristive, memcapacitive and meminductive systems

It is shown that ideal memristors, namely those whose state depends only on the charge that flows through them (or on the history of the voltage), are subject to very strict physical conditions and are unable to protect their memory state against the unavoidable fluctuations, and therefore are susceptible to a stochastic catastrophe.
